3G issue | Telit Cinterion IoT Developer Community

Hello, 

I have problem with EHS5-E module. 

In our country providers turn off the 3G BTS's and module have problem with connection to this network. Time to time it automatically connect to 2G, but its not fine. My question is, exist the firmware, which have disabled 3G networks? Because I can disable it over AT command, but after restart, the default parameters are set.
